The git ________ command provides a byte-wise comparison between two branches to diagnose corruption or discrepancies.
- git diff
- git compare
- git diagnose
- git verify
The correct option is git diff. This command is used to show the differences between two branches at a byte level, making it useful for diagnosing corruption or discrepancies in the branches.
What is a pull request in the context of Git?
- A way to request someone to pull your changes
- A command to pull the latest changes from the remote repository
- A request to merge two branches
- A request to undo the last commit
A pull request is a method used to propose changes to a repository. It allows collaborators to review and discuss the changes before merging them into the main branch. It typically includes details about the changes made and the reason for the changes. This is an essential part of the collaborative workflow in Git.
What is the purpose of the .gitignore file in a Git repository?
- Exclude specific files from version control
- Store sensitive data
- Track changes in the repository
- Create backups automatically
The .gitignore file is used to exclude specific files or patterns from being tracked by Git. This is helpful to avoid cluttering the repository with files that shouldn't be versioned, such as temporary files, build artifacts, or system-specific files.
When stashing changes, what happens to the staged and unstaged modifications in Git?
- Staged changes are preserved, unstaged changes are discarded
- Both staged and unstaged changes are preserved
- Staged changes are discarded, unstaged changes are preserved
- Both staged and unstaged changes are discarded
When you stash changes, Git saves both staged and unstaged changes. This allows you to switch branches without committing changes, and later apply the stash to continue working on the changes.
To delete a tag in Git, use the command git tag -d ________.
- tag-name
- git-delete
- tag-delete
- git-rm
The correct option is a) tag-name. This command deletes the specified tag by providing the tag name after the -d option. It helps in removing unnecessary or incorrect tags from the repository.
A Git Subtree allows you to keep a copy of an external repository in a subdirectory, treating it as a __________ project.
- separate
- nested
- linked
- subtree
The correct answer is subtree. Git subtree is a merging strategy that allows you to insert the contents of a repository into another one, but unlike submodules, the external repository becomes part of the history of the main repository. It is treated as a subtree within the main project.
How should a distributed team structure their Git branches to optimize collaboration?
- Use feature branches for each team member
- Have a central repository with a single branch
- Implement a Git branching strategy, such as Gitflow
- Allow each team member to have their own repository
Distributed Team Branching
To save changes in a new stash, you would use git stash ______.
- save
- create
- push
- store
The command to stash changes is git stash save, which saves the changes in the stash without committing them to the repository. This is useful when you need to switch to a different branch or address an urgent issue.
How can you combine multiple commits into one using Git?
- Use the git merge command with the --squash option to condense multiple commits into one before merging.
- Execute git commit --combine for the commits you want to merge, specifying the commit range.
- Use the git rebase command with the -i (interactive) option to squash, fixup, or reword commits interactively.
- Create a new branch, cherry-pick the desired commits onto it, and then merge the new branch.
Git rebase with the -i option allows for interactive rebasing, including the ability to squash commits together, providing a cleaner history.
What is the importance of Git hooks in automating tasks in CI/CD pipelines?
- Code Deployment
- Code Review
- Automated Testing
- Task Automation
Git hooks are scripts triggered by Git events, such as pre-commit or post-merge. They play a vital role in CI/CD pipelines by automating tasks like code testing and deployment, ensuring a seamless development workflow.
